[0058] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0059] Reference Figure 1-8 , the technical solution of the present invention is as follows: Example

[0060] A highland barley powder grinding device comprises a hollow outer shell 1, wherein two ends of the outer shell 1 are connected, and the outer shell 1 is provided with:

[0061] A feed top plate 10 is arranged in the outer shell 1 and fixedly connected to the outer shell 1. The original highland barley material is placed on the feed top plate 10 for easy feeding later. The top surface of the feed top plate 10 is funnel-shaped. The highland barley material is located at the top center of the feed top plate 10 under the action of gravity, which is convenient for the transfer of the highland barley material later.

[0062] A bran filtering frame 11 is provided in the outer shell 1, and is located below the feed top plate 10. This position is provided to provide a structural basis for transferring highland barley feed;

[0063] A plurality of bran filter elements 110 are arranged in the bran filter frame 11, and the plurality of bran filter elements 110 are arranged in a ring shape at the bottom of the bran filter frame 11, and each group of bran filter elements 110 is composed of a plurality of grinding rollers 1101, and the plurality of grinding rollers 1101 of each group are distributed in a triangular shape. In this way, the highland barley bran is removed from the highland barley by the rotation of the grinding rollers 1101. In addition, the plurality of grinding rollers 1101 of each group are distributed in a triangular shape, and the distribution shape is as shown in FIG. Figure 4 and Figure 5 It can be seen that the distance between the collar edges of the bran filter elements 110 of adjacent groups is getting smaller and smaller, which makes it easier for the highland barley to fully contact with the grinding roller 1101, and the bran on the surface of the highland barley is removed by the rotation of the grinding roller 1101;

[0064] The bran filtering frame 11 includes a discharging plate 111 which is movable up and down at the bottom. The discharging plate 111 can transfer the highland barley after the bran is removed downward by moving up and down, so as to facilitate the subsequent grinding of the highland barley after the bran is removed.

[0065] It should be added that: the bottom of the bran filter frame 11 is provided with a discharge port corresponding to the discharge plate 111, the inner end surface of the discharge port is provided with a plurality of inner convex bodies, the discharge plate 111 is provided with a convex body slot 1110 corresponding to the inner convex body, and the outer side wall of the discharge plate 111 is also provided with a discharge ring 1111, refer to Figure 2 and Figure 3 With such arrangement, when the discharge plate 111 moves downward, the peeled highland barley fruits in the bran filtering frame 11 flow downward from the convex slot 1110 and the discharge ring 1111 in sequence; at the same time, through the cooperation of the convex slot 1110 and the inner convex body, the bran filtering frame 11 can be driven to rotate as a whole when the discharge plate 111 rotates.

[0066] In addition, a guide member 1112 is provided on the top of the discharge plate 111, wherein the guide member 1112 is distributed in a ring shape on the top surface of the discharge plate 111, so that when the discharge plate 111 rotates, the guide member 1112 can be driven to rotate, wherein the guide member 1112 can be composed of an arc-shaped protrusion on the side wall. Then, when the guide member 1112 rotates, the bran can be filtered out of the frame 11, and the unpeeled barley in the barley peeling can be "thrown" out obliquely, thereby facilitating the contact between the barley and the grinding roller 1101, thereby facilitating the peeling process of the barley.

[0067] A feed drive shaft 14 is connected to the axis of the discharge plate 111, and the top of the feed drive shaft 14 passes through the bran filtering frame 11 and the feed top plate 10 in sequence, wherein the setting of the feed drive shaft 14 facilitates the transfer of highland barley from the feed top plate 10 to the bran filtering frame 11; and the feed drive shaft 14 drives multiple groups of bran filtering elements 110 to work, then when the feed drive shaft 14 rotates, it can serve as a driving starter for multiple groups of bran filtering elements 110, driving multiple grinding rollers 1101 to rotate synchronously, thereby realizing the removal of highland barley bran.

[0068] A vertical driving member 15 is arranged in the outer shell 1, and is arranged between the bottom of the feed top plate 10 and the top of the bran filtering frame 11. The bran filtering frame 11 is driven to move up and down as the bran filtering frame 11 rotates. That is, the bran filtering frame 11 is driven to move up and down by the setting of the vertical driving member 15, and the bran filtering frame 11 shakes up and down when moving up and down, which makes it easy for the barley in the bran filtering frame 11 to shake up and down, and further makes the barley fully contact with the grinding roller 1101.

[0069] A bran filtering and grinding assembly 12 is arranged in the outer shell 1, which is arranged on the outer wall of the bran filtering frame 11 and slides up and down along the outer shell 1. That is, the bran filtering and grinding assembly 12 is arranged to grind the filtered highland barley bran to make bran powder.

[0070] Therefore, based on the arrangement of the feed top plate 10, the bran filtering frame 11, the vertical driving member 15 and the bran filtering and grinding assembly 12, the present invention can achieve the effect of mechanically and automatically removing the bran and grinding the bran of highland barley. Compared with the prior art, the present invention can separate the highland barley and the bran thereon, and further grind the bran, so that the bran can be collected and processed, and the bran can be recycled.

[0071] In addition, the present invention also discloses a preferred implementation method for grinding highland barley, collecting highland barley powder and collecting bran powder:

[0072] A collecting base 13 is provided in the outer shell 1 and installed in the bottom of the outer shell 1, and the collection of highland barley powder and bran powder is realized through the collecting base 13;

[0073] The collecting base 13 includes a highland barley grinding base 130 and a bran collecting base 131; the highland barley grinding base 130 and the bran collecting base 131 are provided to respectively realize the collection of highland barley powder and bran powder;

[0074] The bran filtering frame 11 is located in the highland barley grinding seat 130. In this way, the highland barley is ground by the cooperation between the highland barley grinding seat 130 and the bran filtering frame 11, that is, the bran filtering frame 11 moves up and down under the action of the vertical driving member 15. When the highland barley falls into the highland barley grinding seat 130, the distance between the bottom of the bran filtering frame 11 and the inner wall of the highland barley grinding seat 130 is changed with the up and down movement of the bran filtering frame 11, thereby realizing the extrusion of the highland barley. At the same time, the bran filtering frame 11 rotates relative to the highland barley grinding seat 130, thereby further grinding the highland barley, thereby realizing the process of grinding the highland barley into powder;

[0075] The highland barley grinding seat 130 is clamped in the bran collecting seat 131, and the bran collecting seat 131 is connected to the inner wall of the bottom of the outer shell 1. After the highland barley grinding seat 130 is clamped in the bran collecting seat 131, it is installed as a whole in the outer shell 1, so that the installation of the collecting base 13 is realized. After the installation is completed, the highland barley powder and the bran powder can be collected separately, and the clamping between the highland barley grinding seat 130 and the bran collecting seat 131 is released, so that the collected highland barley powder and bran powder can be poured out and collected.

[0076] A driving member is provided in the barley grinding seat 130, and a positioning prism shaft 1301 is connected to the output end of the driving member, and an embedding groove corresponding to the positioning prism shaft 1301 is provided at the bottom of the discharge plate 111, wherein the extension shaft 1301 cooperates with the embedding groove, when the driving member drives the extension shaft 1301 to rotate, the discharge plate 111 can be driven to rotate, and the feed drive shaft 14 can be further driven to rotate. At the same time, when the discharge plate 111 moves up and down, the discharge plate 111 can also slide up and down along the outer wall of the positioning prism shaft 1301 through the embedding groove.

[0077] The working process of the present invention is as follows:

[0078] The first step is to install the collecting base 13: install the collecting base 13 on the outer shell 1, that is, first clamp the highland barley grinding seat 130 on the bran collecting seat 131, then install the bran collecting seat 131 on the bottom of the outer shell 1, and ensure that the extension shaft 1301 is inserted into the embedding groove at the bottom of the discharge plate 111, so as to realize the installation of the collecting base 13 and prepare for collecting highland barley powder and bran powder;

[0079] The second step is to add highland barley: the highland barley to be processed is placed on the top surface of the feed top plate 10, so that the highland barley is transferred to the bran filtering frame 11 through the feed driving shaft 14;

[0080] The third step is bran layering and grinding: start the driving member, the driving member drives the extension shaft 1301 to rotate, and then drives the discharge plate 111 to rotate, and the discharge plate 111 drives the bran filter frame 11 and the feed drive shaft 14 to rotate synchronously, and then further:

[0081] The feed drive shaft 14 rotates to drive the multiple bran filter elements 110 to work simultaneously, so that the grinding roller 1101 in the bran filter element 110 removes the highland barley bran, and the removed bran is ground by the bran filter and grinding assembly 12, and the ground bran falls into the bran collection seat 131 below under the action of gravity;

[0082] When the bran filtering frame 11 rotates, the highland barley stored therein is driven to flow, that is, the highland barley in the bran filtering frame 11 flows outward under the action of centrifugal force, thereby continuously contacting with the grinding roller 1101, which helps to fully remove the bran from the highland barley.

[0083] The fourth step is barley grinding: the discharge plate 111 moves downward, so that the barley with bran removed in the bran filtering frame 11 falls into the barley grinding seat 130, and when the bran filtering frame 11 rotates, it will cooperate with the vertical driving member 15 to synchronously drive the bran filtering frame 11 to move downward, and further by rotating the downward bran filtering frame 11, the barley in the barley grinding seat 130 is first squeezed and crushed, and the crushed barley is ground into powder by the rotation of the bran filtering frame 11.

[0084] Step 5, taking out materials: remove the collecting base 13 from the outer shell 1, and then take out the highland barley powder in the highland barley grinding base 130 and the bran powder in the bran collecting base 131 respectively. Example

[0085] This embodiment discloses the preferred structural features of the feed drive shaft 14, so as to facilitate the transfer of highland barley from the top of the feed top plate 10 to the bran filtering frame 11, and also discloses the preferred structure for realizing the up and down movement of the discharge plate 111 and the blower mechanism for facilitating the outward flow of the fallen bran. The preferred structural arrangement of the feed drive shaft 14 is as follows:

[0087] A feed cavity 141 is also provided on the feed shaft 140, and is arranged in the feed shaft 140. A plurality of feed ports 142 are provided on the outer top thereof, and a plurality of feed ports 143 are provided on the inner bottom thereof. Based on this, the highland barley placed in the feed top plate 10 of the present invention sequentially enters into the bran filtering frame 11 through the feed port 142, the feed cavity 141 and the feed port 143, thereby realizing the process of transferring the highland barley from the feed top plate 10 to the bran filtering frame 11;

[0088] An electric telescopic rod 144 is also provided on the feed shaft 140, which is arranged at the bottom of the feed shaft 140, and its output end is fixedly connected to the top of the discharge plate 111, that is, the discharge plate 111 can be controlled to move up and down by the setting of the electric telescopic rod 144. When the discharge plate 111 moves downward, the barley in the bran filtering frame 11 can be transferred to the barley grinding seat 130; conversely, when the discharge plate 111 moves upward, the bran filtering frame 11 can be closed.

[0089] In addition, based on the setting of the electric telescopic rod 144, the discharge plate 111 and the feed shaft 140 can be set as an integral whole. Then, when the discharge plate 111 rotates, the electric telescopic rod 144 can be used as a connecting piece to transmit and drive the feed shaft 140 to rotate.

Through the setting of the sliding opening, when the discharge plate 111 moves up and down, the integrity of the inner cavity of the outer cover 145 can be ensured, and at the same time, the basis for setting the conditions for subsequent blowing is provided.

[0091] The feed shaft 140 is also provided with a blowing part. Based on the setting of the blowing part, it is beneficial for the bran separated from the barley to be separated from the barley pile. The blowing part preferably includes a mounting cavity opened at the top of the feed shaft 140, a fan 146 is fixedly connected in the mounting cavity, and an air guide 147 is provided at the bottom of the mounting cavity. The air guide 147 extends into the outer cover 145, and a plurality of air outlets are provided on the outer side wall of the outer cover 145;

[0092] Based on the setting of the blowing part, the working process of achieving the separation of bran from the barley pile is as follows: start the fan 146, so that the fan 146 generates a downward airflow, the airflow passes through the installation cavity and the air guide pipe 147 in turn into the outer cover body 145, and finally flows out from the air outlet, and the outflowing airflow flows out in a horizontal direction, and the outflowing airflow blows the bran in the barley pile to flow toward the periphery until the bran adheres to the inner wall of the bran filtering frame 11, which facilitates the subsequent bran grinding process. Example

[0093] The present embodiment also discloses a preferred method for the feed drive shaft 14 to drive the grinding roller 1101 to rotate, and its preferred structural method is as follows: a capping plate is arranged inside the top of the bran filtering frame 11, wherein an outer edge ring is arranged on the outer edge of the capping plate, and the capping plate rotates with the inner wall of the bran filtering frame 11 through the outer edge ring, and the capping plate will not be separated, ensuring that the capping plate is rotatably connected to the inner wall of the bran filtering frame 11, a connecting cavity 112 is arranged inside the capping plate, and a gear 113 is movably sleeved on the outer wall of the feed drive shaft 14, and specifically, the gear 113 is sleeved with the feed drive shaft 14. On the outer wall of the feed shaft 140, the specific socketing method is as follows: an outer flange 1401 is provided on the bottom outer wall of the feed shaft 140, and an outer flange opening corresponding to the outer flange 1401 is provided on the gear 113, wherein the depth of the outer flange opening is greater than the depth of the outer flange 1401, and the outer flange 1401 will not separate from the outer flange opening, so that the cooperation between the outer flange 1401 and the outer flange opening can realize that the feed shaft 140 drives the gear 113 to rotate, and it can realize that when the gear 113 slides up and down with the capping plate, it can ensure that the capping plate slides up and down along the feed shaft 140.

[0094] In addition, an extension shaft 114 is provided at the axis center of the grinding roller 1101, and the extension shaft 114 extends into the connecting cavity 112, and a gear 2 115 is fixedly connected to the outer wall of the extension shaft 114, and two adjacent gear 2s 115 are meshed with each other. At the same time, the gear 2 115 close to the gear 1 113 is meshed with the gear 1 113.

[0095] In this embodiment, the working process of the feed drive shaft 14 driving the grinding roller 1101 to rotate is as follows:

[0096] When the discharge plate 111 rotates, the feed shaft 140 is driven to rotate through the electric telescopic rod 144, and then the gear 113 is driven to rotate. Through the meshing cooperation between gear 2 115 and gear 1 113 and the meshing cooperation between two adjacent gear 2s 115, multiple extension shafts 114 are driven to rotate, and then the rotation of multiple grinding rollers 1101 is driven. Moreover, through the meshing cooperation between two adjacent gear 2s 115, the rotation directions of two adjacent grinding rollers 1101 are further made opposite, which makes it easy to grind off the highland barley bran and realize the process of separating the bran from the highland barley fruit.

[0097] This embodiment discloses a preferred structural composition of the vertical drive member 15, that is, it is easy to realize the up and down movement of the bran filtering frame 11 when it rotates, thereby further grinding the bran and highland barley fruit. Specifically, the preferred structural arrangement of the vertical drive member 15 is as follows:

[0098] The vertical driving member 15 includes two top rods 150 fixedly connected to the bottom of the feed top plate 10, and a resistance ball 151 is arranged at the bottom of the top rod 150, and a slide 152 corresponding to the resistance ball 151 is arranged at the top of the bran filtering frame 11, that is, the cross-section of the slide 152 is composed of an inner arc ball groove and an annular slide, wherein the inner diameter of the inner arc ball groove is larger than the outer diameter of the resistance ball 151, and the annular slide is used for the rotation of the annular slide. Such an arrangement can ensure that the resistance ball 151 will not separate from the inner arc ball groove (in this way, the setting of the resistance ball 151 has a load-bearing effect on the bran filtering frame 11, and at the same time provides a structural auxiliary condition for the subsequent up and down movement of the bran filtering frame 11), and at the same time ensure that the resistance ball 151 can rotate along the inner arc ball groove.

[0099] The slideway 152 includes a lower track 1520, an upper track 1521, an upper track 1522 and a lower track 1523. When the bran filtering frame 11 rotates, the top rod 150 rotates relatively along the slideway 152 because the top rod 150 does not move. Therefore, when the relationship between the abutting ball 151 at the bottom of the top rod 150 and the slideway 152 changes, the upper and lower positions of the bran filtering frame 11 change accordingly. The specific states are divided into the following four states:

[0100] When the abutting ball 151 at the bottom of the top rod 150 is located at the descending path 1523, the bran filtering frame 11 is driven to move downward by the cooperation between the abutting ball 151 and the inner arc-shaped ball groove, so that the bran and highland barley fruit are squeezed downward for easy grinding;

[0101] When the abutting ball 151 at the bottom of the top rod 150 is located at the lower track 1520, the bran filtering frame 11 is maintained at the bottom by the cooperation between the abutting ball 151 and the inner arc-shaped ball groove, which helps to further maintain the grinding of highland barley fruit and bran after extrusion;

[0102] When the abutting ball 151 at the bottom of the top rod 150 is located at the upward path 1521, the bran filtering frame 11 is driven to move upward by the cooperation between the abutting ball 151 and the inner arc-shaped ball groove, so that the bran is squeezed upward and easy to grind; at the same time, it can prepare for the next downward squeezing of the bran filtering frame 11;

[0103] When the abutting ball 151 at the bottom of the top rod 150 is located at the upper track 1522, the bran filtering frame 11 is maintained at the top by the cooperation between the abutting ball 151 and the inner arc-shaped ball groove, so that the bran is squeezed upward and easy to grind; at the same time, it can prepare for the next downward squeezing of the bran filtering frame 11;

[0104] In addition, when the bran filtering frame 11 rotates, under the cooperation of the resistance ball 151 and the inner arc ball groove, the bran filtering frame 11 is driven to circulate to realize that the resistance ball 151 at the bottom of the top rod 150 moves along the downward path 1523, the lower path 1520, the upward path 1521 and the upper path 1522 in sequence, so that the bran filtering frame 11 is shaken up and down, which helps to grind the bran and highland barley fruit, and also helps to fully contact the highland barley with the grinding roller 1101, making it easy for the bran to separate from the highland barley surface.

[0105] In addition, the vertical driving member 15 also includes a telescopic rod, which is connected to the bottom of the feed top plate 10 and the top of the capping plate. The setting of the telescopic rod ensures that the capping plate will not rotate with the rotation of the bran filtering frame 11. This ensures that Example 3 provides the conditions for the feed driving shaft 14 to drive the grinding roller 1101 to rotate. At the same time, the setting of the telescopic rod ensures that the capping plate can move up and down with the bran filtering frame 11. Example

[0106] This embodiment discloses the preferred structural composition of the bran filtering and grinding assembly 12, which can cooperate with the rotation of the bran filtering frame 11 and its up and down movement to easily realize the process of grinding the bran. The preferred structural arrangement is as follows:

[0107] The bran filter and grinding assembly 12 includes a grinding cover 120, which is arranged on the periphery of the bran filter frame 11, so that the bran can be ground through the gap between the bran filter and grinding assembly 12 and the bran filter frame 11, providing bran movement conditions for bran grinding, and its inner surface is funnel-shaped. Through the funnel-shaped setting, fine grinding of bran can be achieved, that is, in the bran grinding process, the bran powder particles after grinding are ground from large to small, and are ground in sequence;

[0108] In order to facilitate the grinding of bran, the inner wall of the grinding outer cover 120 and the outer wall of the bran filtering frame 11 are both provided with grinding protrusions A121, that is, the grinding protrusions A121 help to fully grind the bran, wherein the grinding protrusions A121 on the outer wall of the bran filtering frame 11 and the grinding protrusions A121 on the grinding outer cover 120 are staggered, so that the grinding of bran is achieved through the gap between the upper and lower grinding protrusions A121, and when the bran filtering frame 11 moves up and down, the distance between the upper and lower grinding protrusions A121 in the vertical direction changes, a part of the bran is squeezed, and then the grinding protrusions A121 on the outer wall of the bran filtering frame 11 rotate relative to the grinding protrusions A121 on the grinding outer cover 120, which further helps to grind the bran;

[0109] The bran filtering and grinding assembly 12 includes a bran inlet 122, which is arranged on the side wall of the bran filtering frame 11, that is, the bran separated from the highland barley is blown to the periphery and then enters the bran inlet 122, thereby entering between the grinding cover 120 and the bran filtering frame 11, which is helpful for grinding.

[0110] At the same time, the inner end face of the bran inlet 122 is arranged in an arc shape. Such arrangement can realize the retention of bran by the bran inlet 122, which is not only convenient for the bran to escape outward after entering the bran inlet 122, but also because the bran located in the bran inlet 122 continuously rotates with the bran filtering frame 11, which can drive the bran placed in the bran inlet 122 to rotate synchronously, and prevent the bran from escaping from the bran inlet 122; in addition, because the bran filtering frame 11 rotates, the bran in the bran inlet 122 is driven to rotate, and based on the arc shape of the inner end face of the bran inlet 122, when the bran enters between the grinding outer cover 120 and the bran filtering frame 11, the bran can be pre-treated at the edge of the outer port of the bran inlet 122, so that the bran can be formed into a rolled strip, which is easy to grind the bran through the grinding protrusion A121 later.

[0111] Finally, the bran filter grinding assembly 12 includes a slider 123 fixed to the inner wall of the grinding outer cover 120. The slider 123 is set to limit the movement of the grinding outer cover 120, that is, to slide up and down along the inner wall of the outer shell 1, wherein a slide groove for the slider 123 to slide up and down is set on the inner wall of the outer shell 1;

[0112] In order to enhance the grinding effect of the bran, a return spring may be provided on the connecting plate between the top surface of the slider 123 and the inner top surface of the chute. By setting the return spring, the initial state of the grinding outer cover 120 is maintained. When the bran filtering frame 11 moves downward, the grinding outer cover 120 may be driven to move downward first until the bottom end surface of the grinding outer cover 120 contacts the inner bottom end surface of the chute, thereby stopping the downward movement trend of the grinding outer cover 120, while the bran filtering frame 11 continues to move downward, thereby further realizing the extrusion grinding of the bran and the highland barley fruit below. Example

[0113] This embodiment also discloses a preferred method of the highland barley grinding seat 130 and the bran collecting seat 131, which is convenient for collecting the bran and highland barley after grinding. At the same time, based on this method, an implementation method for driving the discharge plate 111 to rotate is also disclosed.

[0114] 1. The preferred configuration of the highland barley grinding seat 130 and the bran collecting seat 131 is as follows:

[0115] The setting of the highland barley grinding seat 130 is as follows: the highland barley grinding seat 130 includes a positioning seat 1300 and a grinding base 1306, wherein the grinding base 1306 is rotatably connected to the top of the positioning seat 1300, and at the same time, the inner bottom surface of the grinding base 1306 and the bottom surface of the discharge plate 111 are provided with a plurality of grinding protrusions B. When the highland barley falls from the peripheral side of the discharge plate 111 and is placed in the grinding base 1306, the discharge plate 111 is driven by the vertical driving member 15 to move downward to realize the extrusion of the peeled highland barley in the grinding base 1306. At the same time, through the rotation of the discharge plate 111 and the setting of the grinding protrusion B, the peeled and extruded highland barley in the grinding base 1306 can be ground, and the ground highland barley is located in the grinding base 1306.

[0116] The bran collecting seat 131 is arranged as follows: the bran collecting seat 131 is threadedly connected to the outer shell 1. Such arrangement facilitates the connection between the bran collecting seat 131 and the outer shell 1. The threaded connection method is adopted to achieve the detachable connection between the bran collecting seat 131 and the outer shell 1, so as to facilitate the subsequent removal of the bran collecting seat 131 and thereby take out the bran powder after grinding.

[0117] At the same time, the bran collecting seat 131 is composed of an outer edge 1310 and a bottom ring 1311, and the threaded end of the bran collecting seat 131 is arranged on the outer wall of the outer edge 1310, so that a bran powder collecting ring cavity is formed between the inner wall of the outer edge 1310 and the outer wall of the grinding base 1306, and the bran powder collecting ring cavity is opposite to the feeding area between the bran filter grinding assembly 12 and the bran filter frame 11, so that the bran after grinding enters the bran powder collecting ring cavity to realize the collection of bran powder.

[0118] A limiting protrusion 1312 is provided in the bottom ring 1311, and a limiting groove 1313 corresponding to the limiting protrusion 1312 is provided at the bottom of the outer wall of the positioning seat 1300. In this embodiment, the connection between the positioning seat 1300 and the bottom ring 1311 is achieved through the cooperation of the limiting protrusion 1312 and the limiting groove 1313, that is, when the bran collecting seat 131 is threadedly connected to the bottom of the outer shell 1, it will drive the positioning seat 1300 to adjust its position, and the positioning seat 1300 is supported by the setting of the limiting protrusion 1312; at the same time, this combination method is adopted to facilitate the discharge of bran powder, that is, the bran collecting seat 131 is screwed out from the bottom of the outer shell 1, and then the positioning seat 1300 is removed. At this time, the bottom of the bran powder collecting ring cavity is in an open state, which is convenient for removing the bran powder.

[0119] 2. Based on the structural setting of the highland barley grinding seat 130, this embodiment also discloses an implementation method for driving the discharge plate 111 to rotate:

[0120] A fixing groove is provided on the top of the positioning seat 1300 , and a driving motor is fixedly connected therein, and a driving shaft 1302 is fixedly connected to the output end of the driving motor.

[0121] 3. Based on the setting of the driving shaft 1302, this embodiment also preferably discloses an implementation method in which the grinding base 1306 rotates in the opposite direction relative to the bran filtering frame 11, which helps to achieve a process of fully grinding the highland barley. The preferred settings are as follows:

[0122] The outer side wall of the cylindrical end of the driving shaft 1302 is fixedly connected with a gear 3 1303, so when the driving shaft 1302 rotates, the driving gear 3 1303 rotates;

[0123] A positioning shaft 1304 is fixedly connected to the bottom of the fixed groove, and a gear 4 1305 is fixedly connected to the outer wall of the positioning shaft 1304, and the gear 4 1305 is meshed with the gear 3 1303 for transmission. When the gear 3 1303 rotates, the gear 4 1305 is driven to rotate;

[0124] A gear ring 1307 is fixedly connected to the bottom of the grinding base 1306, and the gear ring 1307 is meshed with gear four 1305. When gear four 1305 rotates, the gear ring 1307 is driven to rotate, and then the grinding base 1306 is driven to rotate. Due to the guidance of gear four 1305, the rotation direction of the gear ring 1307 is opposite to the rotation direction of the drive shaft 1302, so that the rotation direction of the grinding base 1306 is opposite to the rotation direction of the bran filtering frame 11, which helps the grinding protrusion B to grind the barley in the grinding base 1306.

[0125] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
